Thanks! Feel free to add my: > > Reported-by: Marek Szyprowski > > Tested-by: Marek Szyprowski Hi Marc, Linux-next still fails to boot on Exynos5422 boards, so I wonder if you applied the fix? Instead of silent fail there is now "Unable to handle kernel paging request at virtual address f0836644", so it is slightly different. See the dmesg: https://krzk.eu/#/builders/21/builds/3542/steps/15/logs/serial0 Best regards, Krzysztof
